Abstract: Silver coated metal-o-seals (Helicoflex) and metal-c-seals (Advanced products) have been tested within a range of temperatures from 20$^\circ$ to 45$^\circ$C. These types of seals are intended for application in the vacuum vessel of the fusion experiment TEXTOR. The investigations include circular ($\phi$ 500 mm) and noncircular (race track 750x100 mm and 300x100 mm) shapes. The tightening forces per cm length are in the range from 200 daN/cm to 420 daN/crn. The Helium leak rates have been measured after assernbling at room temperature, during the thermal cycling and after long time test at some 450$^\circ$C.
